High-magnetic field phase diagram and failure of magnetic Grüneisen scaling in LiFePO
J. Werner, S. Sauerland, C. Koo +4
We report the magnetic phase diagram of single-crystalline LiFePO in magnetic fields up to 58~T and present a detailed study of magneto-elastic coupling by means of high-resolu…
Synthesis and Magnetism of a LiFeSiO Single Crystal
Waldemar Hergett, Martin Jonak, Fabian Billert +5
A macroscopic single crystal of -Li\(_2\)FeSiO\(_4\) has been grown by means of the high-pressure optical floating-zone technique. Static magnetic susceptibility im…
The decisive role of magnetic anisotropy in honeycomb layered LiNiSbO and NaNiSbO
J. Werner, W. Hergett, J. Park +4
The decisive role of magnetic anisotropy even in systems with small anisotropy is illustrated for the honeycomb-layered antiferromagnets The decisive role of magnetic anisotropy in…
High-frequency EPR study on CuCu- and CoCo-metallacrown complexes
C. Koo, J. Park, J. Butscher +2
High-frequency/high-field electron paramagnetic resonance studies on two homo-nuclear 12-MC-4 metallacrown complexes CuCu and CoCo are presented. For CuCu, our data imp…
Magnetic phase diagram of EuCuSi derived from thermal expansion and magnetostriction studies
Liran Wang, Lars Wallbaum, Changhyun Koo +3
Precise thermal expansion and magnetostriction studies of the intermetallic compound EuCuSi in the temperature range between 5 and 300 K are presented. A clear sign of magn…
Manifestation of Spin Selection Rules on the Quantum Tunneling of Magnetization in a Single Molecule Magnet
J. J. Henderson, C. Koo, P. L. Feng +5
We present low temperature magnetometry measurements on a new Mn3 single-molecule magnet (SMM) in which the quantum tunneling of magnetization (QTM) displays clear evidence for qua…
